Was Hillary Clinton wearing ‘Life Alert’ emergency device in New York?

During her speech in New York City, Hillary Clinton complained she was suffering from exhaustion resulting from protesting President Trump and appeared to be wearing a Life Alert emergency button necklace.

It was first brought to our attention by Twitter user @ComfortablySmug who posted a photo of Clinton posing with a fan while she was in Central Park for the Ozy Fest:

Here’s a zoomed-in version of the photo, focusing mainly on the necklace:

The necklace does look very similar to the Life Alert emergency device made famous for the “I’ve fallen and I can’t get up!” commercials:

What do you think? Is that what Hillary was wearing?
